摘　　要：传统故障录波装置常使用实时总线和实时操作系统进行模拟量和开关量的采样,实时操作系统要求CPU处理能力高,能实时完成对采样数据的处理。采用改进的非实时总线同步方法,有效降低CPU的负荷,从而降低故障录波装置对操作系统的实时性要求,提高产品设计的通用性。Traditional Fault Recorder devices often use real-time bus and real-time operating system to sample analog data.However,the real-time sampling system requires high CPU processing capacity and can complete the processing of sampling data in real time.The improved non real-time bus synchronization method is adopted to effectively reduce the load of CPU,so as to reduce the real-time requirements of fault recording device for operating system and improve the universality of product design.

关 键 词：故障录波 实时操作系统 非实时总线
